Bacterial non-specific acid phosphatases normally catalyze the dephosphorylation of a variety of substrates. As shown previously the enzymes from Shigella flexneri and Salmonella enterica are also able to catalyze the phosphorylation of inosine to inosine monophosphate and D-glucose to D-glucose 6-phosphate (D-G6P) using cheap pyrophosphate as the phosphate donor. After optimization high yields (95%) are achieved in the latter reaction and we show here that it is possible to use these enzymes in a preparative manner. This prompted us to investigate by using 31P NMR and HPLC also the phosphorylation of a broad range of carbohydrates and alcohols. Many cyclic carbohydrates are phosphorylated in a regioselective manner. Non-cyclic carbohydrates are phosphorylated as well. Phosphorylation of linear alcohols, cyclic and aromatic alcohols is also possible. In all cases the acid phosphatase from Shigella prefers a primary alcohol function above a secondary one. We conclude that these enzymes are an attractive alternative to existing chemical and enzymatic methods in the phosphorylation of a broad range of compounds.

Enzymatic glycosidation using sugar oxazolines 1-3 having a carboxylate group as glycosyl donors and compounds 4-6 as glycosyl acceptors was performed by employing a chitinase from Bacillus sp. as catalyst. All the glycosidations proceeded with full control in stereochemistry at the anomeric carbon of the donor and regio-selectivity of the acceptor. The N,N?-diacetyl-6?-O- carboxymethylchitobiose oxazoline derivative 1 was effectively glycosidated, under catalysis by the enzyme, with methyl N,N?-diacetyl-beta- chitobioside (4), pent-4-enyl N-acetyl-beta-d-glucosaminide (5), and methyl N-acetyl-beta-d-glucosaminide (6), affording in good yields the corresponding oligosaccharide derivatives having 6-O-carboxymethyl group at the nonreducing GlcNAc residue. The N,N?-diacetyl-6-O-carboxymethylchitobiose oxazoline derivative 2 was subjected to catalysis by the enzyme catalysis; however, no glycosidated products were produced through the reactions with 4, 5, and 6. Glycosidation reactions of the beta-d-glucosyluronic-(1?4)-N-acetyl-d- glucosamine oxazoline derivative 3 proceeded with each of the glycosyl acceptors, giving rise to the corresponding oligosaccharide derivative having a GlcA residue at their nonreducing termini in good yields.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 92420-89-8 is helpful to your research., Related Products of 92420-89-8

Inducible AmpC beta-lactamases deactivate a broad-spectrum of beta-lactam antibiotics and afford antibiotic resistance in many Gram-negative bacteria. The disturbance of peptidoglycan recycling caused by beta-lactam antibiotics leads to accumulation of GlcNAc-1,6-anhydroMurNAc-peptides, which are transported by AmpG to the cytoplasm where they are processed into AmpC inducers. AmpG transporters are poorly understood; however, their loss restores susceptibility toward beta-lactam antibiotics, highlighting AmpG as a potential target for resistance-attenuating therapeutics. We prepare a GlcNAc-1,6-anhydroMurNAc-fluorophore conjugate and, using live E. coli spheroplasts, quantitatively analyze its transport by AmpG and inhibition of this process by a competing substrate. Further, we use this transport assay to evaluate the function of two AmpG homologues from Pseudomonas aeruginosa and show that P. aeruginosa AmpG (Pa-AmpG) but not AmpP (Pa-AmpP) transports this probe substrate. We corroborate these results by AmpC induction assays with Pa-AmpG and Pa-AmpP. This fluorescent AmpG probe and spheroplast-based transport assay will enable improved understanding of PG recycling and of permeases from the major facilitator superfamily of transport proteins and may aid in identification of AmpG antagonists that combat AmpC-mediated resistance toward beta-lactam antibiotics.

Reaction between copper(II)- and zinc(II)-nitrates and 2,2?-dipyridyl(N-propenyl)amine (Prdpa) affords 1:1 complexes M(Prdpa)(NO3)2 (M = Cu, 1; M = Zn, 5) for both metal ions and a 1:2 adduct M(Prdpa)2(NO3)2 (2) for copper only. In ethanol 1 dissociates to form 2 and copper nitrate. X-ray diffraction studies on 1, 2 and 5, and on the 2,2?-dipyridylamine (Hdpa) analogue of 1, Cu(Hdpa)(NO3)2 (4), are reported. The metal centres exhibit square pyramidal (1) or distorted octahedral (2, 4, 5) primary coordination spheres. Bridging nitrate groups linking Cu atoms in 1 and 4 result in -Cu-O-N-O-Cu- chains, which in the case of 4 are extensively cross-linked by N – H¡¤¡¤¡¤ONO2 H-bonding into 3D-arrays. Intermolecular C – H¡¤¡¤¡¤ONO2 interactions are apparent in the solid-state structure of 2. The structural effects of replacing the N – H atom on Hdpa by a propenyl group in 6-coordinate Cu(II) complexes are assessed. Crown Copyright

A large number of new [Ru”([9]aneS3)(L)Cl]complexes (where L is a polypyridyl bidentate ligand) were synthesized from the precursor [Ru([9]aneS3)(dmso)Cl2] in the search for new DNA intercalators. The ancillary ligands used have different molecular architectures which include cross bridges, pyridyl units, phenanthroline and diamine derivatives. The related complex [Ru([9]aneS3)(ind)ClJ, containing the monodentate ligand indazole, was also prepared. The diimine complexes [Ru([9]aneS3)(pdi)Cl]+ and [Ru([9]aneS3)(phi)Cl]+ were prepared in situ from the ligands pda (o-phenylenediamine) and dap (phenanthrene-9, 10-diamine), respectively, via Ru assisted amine/imine oxidation. All complexes were characterised through ‘H NMR, IR, UV-Vis and electrospray mass spectrometry. Furthermore, the PF6 salts of seven [Ru([9]aneS3)(L)Cl]+ and [Ru([9]aneS3)(dip)Cl]BF4 (dip = 4, 7-diphenylphenanthroline) have been investigated by X-ray single crystal diffraction. The crystal structures are presented and analysed in terms of the molecular assemblies of the complex cations and anions and the molecular hydrogen bonding interactions.

Following a program undertaken to identify hit compounds against NADH:ubiquinone oxidoreductase (PfNDH2), a novel enzyme target within the malaria parasite Plasmodium falciparum, hit to lead optimization led to identification of CK-2-68, a molecule suitable for further development. In order to reduce ClogP and improve solubility of CK-2-68 incorporation of a variety of heterocycles, within the side chain of the quinolone core, was carried out, and this approach led to a lead compound SL-2-25 (8b). 8b has IC50s in the nanomolar range versus both the enzyme and whole cell P. falciparum (IC 50 = 15 nM PfNDH2; IC50 = 54 nM (3D7 strain of P. falciparum) with notable oral activity of ED50/ED90 of 1.87/4.72 mg/kg versus Plasmodium berghei (NS Strain) in a murine model of malaria when formulated as a phosphate salt. Analogues in this series also demonstrate nanomolar activity against the bc1 complex of P. falciparum providing the potential added benefit of a dual mechanism of action. The potent oral activity of 2-pyridyl quinolones underlines the potential of this template for further lead optimization studies.
